“…It has been reported that tumour thrombus demonstrates increased FDG accumulation when compared to benign thrombus [4][5][6][7]. F-18 FDG PET imaging has demonstrated malignant thrombus caused by numerous primary carcinomas including choriocarcinoma, follicular thyroid carcinoma, rectal carcinoma and renal cell carcinoma [7][8][9][10][11]. Testicular cancer is one of the malignancies known to have the potential to develop a venous tumour thrombosis [12].…”

21-year-old male presented with recently diagnosed metastatic nonseminomatous germ cell tumour and left orchidectomy. CT demonstrated mixed density in the inferior vena cava (IVC) extending from the union of the common iliac veins to the level of the liver just below the confluence of the hepatic veins. Retroperitoneal nodal disease and deposits in the left lung were suspicious for metastatic deposits. F-18Flurodeoxyglucose (FDG) PET/CT images demonstrated avid FDG uptake within the lumen of the IVC from the level of the renal veins, with extension into both renal veins, to the level of T10. While benign and malignant thrombi have previously been demonstrated on F18-FDG PET imaging, this case highlights the use of F-18 FDG PET/CT when identifying tumour thrombosis in patients with nonseminomatous germ cell tumour.

“…[4][5][6][7][8][9][10][11][12] However, except for elevated FDG activity, the findings of tumor thrombus at different blood vessels are quite variable. [4][5][6][7][8][9][10][11][12] In our case, we describe a different pattern of tumor thrombus in the entire length of left ovarian arteries and veins, which appears similar to the findings of retroperitoneal fibrosis on FDG PET/CT as previously described.

FDG PET/CT Appearance of Tumor Thrombus of Ovarian Vessels Masquerading as Retroperitoneal Fibrosis

A 23-year-old woman with recurrent uterine endometrial stromal sarcoma underwent FDG PET/CT, which showed pelvic recurrence and multiple pulmonary metastases. In addition, increased activity in a vertical soft tissue mass along the left ureter was noted, which appears similar to retroperitoneal fibrosis on PET/CT images. However, pathological examination demonstrated that the elevated FDG activity in this mass was a result of tumor thrombus from endometrial stromal sarcoma in the left ovarian arteries and veins.

“…Elevated HCG level indicates increased tumor activity and its energy demand, which makes most gestational trophoblastic disease, including choriocarcinoma, suitable for FDG PET detection. [1][2][3][4][5][6][7] In this case, FDG uptake of metastatic lesions is low, reflecting poor glucose utility. Review of the literature showed only a few reported cases of low FDG avidity in metastatic lesions of gestational trophoblastic disease.…”

Poor FDG Avidity in a Case of Metastatic Pulmonary Choriocarcinoma

Gestational trophoblastic disease is a rare complication of pregnancy, representing a group of tumors from the placental trophoblast. Choriocarcinoma is the most malignant tumor in gestational trophoblastic disease, and is known as having good avidity of F-18 fluorodeoxyglucose (FDG). In this study, we report a case of recurrent pulmonary metastasis of choriocarcinoma with poor FDG avidity. To our knowledge, this is the first report of tissue-proven poor FDG-avid metastatic choriocarcinoma.
